This article examines the evidence for the empirical argument that there is a slippery slope between the legalization of voluntary and non-voluntary euthanasia. The main source of evidence in relation to this argument comes from the Netherlands. The argument is only effective against legalization if it is legalization which causes the slippery slope. Moreover, it is only effective if it is used comparatively-to show that the slope is more slippery in jurisdictions which have legalized voluntary euthanasia than it is in (...) jurisdictions which have not done so. Both of these elements are examined comparatively. (shrink)

Slippery slope arguments appear regularly whenever morally contested social change is proposed. Such arguments assume that all or some consequences which could possibly flow from permitting a particular practice are morally unacceptable.Typically, “slippery slope” arguments claim that endorsing some premise, doing some action or adopting some policy will lead to some definite outcome that is generally judged to be wrong or bad. The “slope” is “slippery” because there are claimed to be no plausible halting points between the initial commitment to (...) a premise, action, or policy and the resultant bad outcome. The desire to avoid such projected future consequences provides adequate reasons for not taking the first step.Thus the legalization of abortion in limited circumstances is asserted to lead down the slippery slope towards abortion on demand and even infanticide; and the legalization of assisted suicide to lead inexorably to the acceptance of voluntary euthanasia and subsequently to the sanctioning of the practice of nonvoluntary euthanasia – even involuntary euthanasia of “undesirable” individuals.

This paper explores the common argument proposed by opponents of the legalization of euthanasia that permitting ending a patient’s life at their request will lead to the eventual legalization of terminating life without request. The author’s examination of data does not support the conclusion that a causal connection exists between legalizing ending of life on request and an increase in the number of cases without request.
